Product details
Overview
ISL43141IVZ from Renesas (formerly Intersil) is a quad SPST analog switch with four normally open (NO) channels, designed for precision signal routing in low-voltage, battery-powered systems. It operates from single 2V–12V or dual ±2V–±6V supplies, delivers 50Ω typical RON at ±4.5V/10.8V, 30ns tON, and 1nA max leakage at 85°C - enabling high-fidelity audio/video switching and portable medical sensor multiplexing.
For engineers reviewing the ISL43141IVZ datasheet, ISL43141IVZ pinout, ISL43141IVZ application, or ISL43141IVZ equivalent, this device is selected for ultra-low power consumption (<1μW), tight RON matching (≤2Ω), minimal charge injection (≤5pC), and compatibility with TTL/CMOS logic across 2.7V–12V supply ranges.
Technical Context
The ISL43141IVZ uses CMOS transmission-gate architecture with independent digital control per channel, supporting both single-supply (V− tied to GND) and bipolar configurations. Its level-shifting logic interface ensures consistent 0.8V/2.4V input thresholds across V+ = 2.7V–12V, while internal ESD diodes (2000V HBM) clamp analog pins between V+ and V−.
Signal integrity is maintained via 12Ω RON flatness over full analog range, <−90dB crosstalk, >90dB off isolation at 100kHz, and 14pF CCOM(ON) - making it suitable for high-frequency multiplexing up to 100MHz in 50Ω systems without gain peaking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (±4.5V) | 50Ω typical - enables low insertion loss in precision instrumentation and DAC/ADC signal paths |
| tON/tOFF (10.8V) | 30ns / 18ns - supports high-speed data acquisition and video switching up to ~15MHz |
| Charge Injection | ≤5pC - minimizes voltage glitch on sampled-hold nodes and sensor front-ends |
| ILEAKAGE (85°C) | ≤5nA max - preserves accuracy in high-impedance biomedical and electrochemical sensing |
| Supply Range | Single 2.7V–12V or dual ±2V–±6V - accommodates Li-ion, coin-cell, and industrial rail voltages |
| Off Isolation | >90dB at 100kHz - suppresses signal bleed between unused channels in multi-signal systems |
| Package | 16-lead TSSOP (M16.173) - 5mm × 4.4mm footprint with 0.65mm pitch for space-constrained PCBs |
Pinout & Package
ISL43141IVZ is housed in a 16-lead TSSOP package (JEDEC MO-153, pkg drawing M16.173) with exposed thermal pad (not electrically connected). Pin functions are identical across SOIC/TSSOP/QFN variants per datasheet Figure 2 (top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Drives analog switch gates and internal logic; sets upper analog signal limit (0V to V+) |
| V− | Negative supply rail | Drives analog switch gates; tied to GND for single-supply operation; sets lower analog limit |
| GND | Logic ground reference | Reference for digital inputs only; no connection to analog signal path |
| IN1–IN4 | Digital control inputs | TTL/CMOS-compatible; logic "1" (≥2.4V) closes NO switches; "0" (≤0.8V) opens them |
| COM1–COM4 | Analog common terminals | Input/output bidirectional ports; each connects to its respective NO pin when enabled |
| NO1–NO4 | Normally open analog terminals | Open-circuit when INx = 0; connect to COMx when INx = 1; no internal pull-up/down |
| N.C. | No internal connection | Pin 13 (TSSOP); must be left unconnected or grounded per layout best practices |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent SPST NO switches | Enables discrete routing of four separate analog signals without inter-channel coupling |
| 12Ω RON flatness (±4.5V) | Maintains amplitude linearity across full signal swing - critical for audio and video fidelity |
| 2Ω RON matching between channels | Ensures consistent gain/attenuation in multi-channel instrumentation amplifier networks |
| 1nA max leakage at 85°C | Preserves DC accuracy in high-Z sensor interfaces (e.g., pH electrodes, thermopiles) |
| 2000V HBM ESD rating | Eliminates need for external protection in handheld and field-deployable equipment |
| Pb-free RoHS-compliant packaging | Meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity for standard SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | 50Ω RON (typ), 45ns tON, 16-pin SOIC only, no TSSOP option | Higher tON limits use in >10MHz sampling; SOIC footprint increases board area vs TSSOP | Select when SOIC is preferred and 45ns switching suffices; verify 1nA leakage spec at 85°C |
| ADG1411BRUZ | 1.8Ω RON (typ), 17ns tON, 16-pin TSSOP, but requires ≥4.5V supply minimum | Superior RON and speed, but incompatible with 2.7V–3.3V battery rails used by ISL43141IVZ | Select for high-precision, higher-voltage systems where RON matching <1Ω is critical |
Compared with MAX4617ESE+ and ADG1411BRUZ, the ISL43141IVZ uniquely balances ultra-low leakage, wide supply flexibility (2.7V–12V), and TSSOP packaging - making it optimal for space-constrained, battery-operated designs requiring long-term DC stability.

FAQ
What supply voltage ranges does the ISL43141IVZ support?
The ISL43141IVZ supports single-supply operation from 2.7V to 12V (V− tied to GND) or dual-supply operation from ±2V to ±6V. At 2.7V, RON rises to 200Ω and tON increases to 120ns; performance improves progressively up to 12V, where RON is 50Ω and tON is 30ns. The ISL43141IVZ datasheet specifies full functionality across all these ranges.
Does the ISL43141IVZ require external ESD protection?
No, the ISL43141IVZ incorporates 2000V HBM ESD protection on all pins per MIL-STD-883 Method 3015.7, eliminating the need for external TVS diodes in most handheld and portable applications. However, if analog signals may exceed V+ or V−, series current-limiting resistors (e.g., 1kΩ on digital inputs) are recommended per datasheet Figure 8.
How does the ISL43141IVZ handle logic-level compatibility across different supply voltages?
The ISL43141IVZ maintains TTL-compatible thresholds (VINH ≥ 2.4V, VINL ≤ 0.8V) across its entire 2.7V–12V V+ range. Internal level shifters translate logic inputs to gate drive voltages referenced to V+ and V−, ensuring reliable switching regardless of supply voltage - a key advantage over non-level-shifted analog switches.
Can the ISL43141IVZ be used in AC-coupled high-frequency applications?
Yes - the ISL43141IVZ achieves >90dB off isolation at 100kHz and maintains flat frequency response beyond 100MHz in 50Ω systems (per Figure 18). Its 7pF COFF and 14pF CCOM(ON) minimize capacitive loading, making it suitable for RF tee-switching, ultrasound beamforming, and high-speed multiplexing where signal integrity above 10MHz is required.
What is the thermal performance of the ISL43141IVZ in TSSOP packaging?
The ISL43141IVZ in 16-lead TSSOP has a typical θJA of 150°C/W under JEDEC JESD51-2 conditions. With <1μW quiescent power, self-heating is negligible (<0.15°C rise at ambient), allowing operation up to +85°C junction temperature. The exposed pad variant is not offered - thermal relief relies on copper pour and via stitching per standard TSSOP layout guidelines.
